FOLDING CHAIR.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed April 2, 1906. Serial No. 309,501.

To all whom it may concern:

Be it known that I, GUILLERMO GALLA- HAN, of San Gabriel, in the county of Los Angeles, in the State of California, have invented a new or Improved Folding Chair, of which the following 1s a full, clear, and exact description or specification, reference being had to the annexed drawings, and to the letters and figures marked thereon.

My said invention which relates to certain new and useful improvements in folding chairs, has for its object, to render such chairs much stiffer in their ointed parts than hitherto, and this object is effected by joints wherewith the seat is connected to the back legs and back of the chair, and the front legs are connected to the front part of the seat thereof; the connections or joints of the legs both at the back of the seat, being such that the seat can be folded up against the back part of the chair, and the front legs against the underpart of the seat of the chair, as hereinafter more fully described.

Upon the annexed drawings, Figure 1, is a side elevation of a chair constructed according to my resent invention when in the unfolded con ition or ready for being sat in, or upon. F-i 2, is another side elevation of the same 0 air when in the folded condition, and ready for being easily carried about. Fig. 3, is a front elevation of the said chair; Fig. 4, an elevation looking at the rear thereof; and Fig. 5, a plan of my improved folding chair, shown as provided with a seat of plaited cane strips. Fig. 6, is a front elevation; Fig. 7, an elevation at the main face corresponding to Fig. 6; and Fig. 8, a plan on an enlarged scale of the joint of the left front log, by which said front leg is connected. to the under art of the front of the seat. Fig. 9, is an e go or front elevation, on a correspondin enlarged scale, of the joint by which t e left rear end of the seat is con nected to the left rear leg or back of the chair, this joint being shown with its parts in the osition they occupy, when the chair is in the olded condltion corresponding to Fig. 2. Fig. 10, is a side elevation corresponding to Fig. 9, that is to say, with its parts in the position correspondin to the chair when folded as shown at F1 2. Fig. 11, is another side elevation o the joint shown at Figs. 9 and 10, but with the parts in the folded down position or correspondin with the condition of the chair as shown at igs. 1,

3 and 4. Fig. 12, is a front elevation corresponding to Fig. 1.1, and Fig. 13, is a plan corres ending to Fig. 11.

In Figs. 1 to 5, the bars f orinin legs and back of the chair are mar (ed. A, the front legs B, and the seat C. The bars A, are connected transversely by the cross members D, D, D, D, and the front legs B, are connected transversely by the cross members E, E, E. The seat C, is connected hingewise to the back bars and legs A, by the upper part F, of the joints, whose lower part is marked G. The upper and lower parts F, and G, of each rear oint, are attached to the under part of the seat C, by screws inserted through holes a, b, and 0, shown in the upper part F, and by screws d, to the rear legs as shown at Figs. 1, 2, 10 and 1 1. The upper and lower parts F, and G, of each rear oint are not only connected by the pivot e, Figs. 1, 2, 10 and 11, but these parts are also connected by a bar H, Figs. 2, 9, 10, 11 and 12, whose u per end is connected ivotally by the pin to the upper part of each rear joint, and whose lower end is connected to the lower part G, of each rear joint, by the pinching bolt g, passing through a hole therein and through the uadrantal slot I, in the art G, of each 0' the rear joints. The bol t g, being provided with a nut h, for tightening the parts, while to still more securely bind the parts together, when the chair is in the opened condition, a thumbscrew J, passing through the bar H, is screwed into the tapped boss K, Figs. 1, 2, 9, 10, 11 and 12.

With respect to the front legs B, these are connected to the front under part of the seat C, by the 'oints shown at Figs. 1, 2, 3, 6, 7 and 8. e front le s B, are each driven tight into the sockets Each socket L, is connected b the pivot pin '5, to the up or part M, of t e front 'oints, and is provl ed with a pinching nut screwed on a pin or stud projectin from each socket L, through a quadrantal s ot N, in the wing of the part M, of each front leg joint. By tightening or loosenin the nuts k, the front legs B, are capable of eing fastened in either the open osition shown at Figs. 1, 3 and 4, or in the olded position shown at Fi 2 The extreme folded position of the front legs B, is shown b dotted lines in Fig. 2.

It is ere explained that as a chair has right and left ends, the joints for connecting the legs with the right and left ends of the the back back, seat, and front legs are necessarily made right and. left, and that for the joints which are to be used for the right end of a chair, the parts constituting the right end joints, are 1n reverse position to corresponding arts in the left end joints, as more particular y shown at Figs. 3 and 4 of the annexed drawings.

Having now described the nature of my said invention, and the best system, mode or manner, I am at present acquainted with, for carrying the same into practical effect, I desire to observe in conclusion that What I consider to be novel and original and therefore claim as the invention to be secured to me by Letters Patent, is as follows:

In a foldin chair, a seat hingedly connected to the bac and rear legs, a member connected to the rear legs and rovided with a quadrantal slot, a bar pivota ly connected to the seat at one end, a bolt and nut on the other end of the bar engaging the said slot for locking the seat in position, said member having a ta )ped hole, a thumb screw on the said bar adapted to engage with the said tapped hole when the seat is in horizontal position, front legs hinged to the seat, a quadrantal vertical wing secured to the seat and provided with a quadrantal slot, a pinching stud and nut projecting from the said leg and enga ing the last named slot for locking the front legs in osition.

In testimony whereof have hereunto set my hand and seal in the presence of two subscribing witnesses.
